User create via API, Zoom One plan option

I’m having trouble assigning a Zoom Phone plan to new users. We recently upgraded to Zoom One Enterprise Plus US/CA Unlimited but I’m not seeing a plan code for that sku.

I’ve tried options 16, 134217728, and 33554432 and the end result is the user being assigned only Zoom Phone Basic. *Edit: Users are US based.

Is there a new plan code that’s missing from the documentation shown below?
Zoom User API.

{
“action”: “autoCreate”,
“user_info”: {
“email”: “user@domain.com”,
“type”: 2,
“first_name”: “First”,
“last_name”: “Last”,
“display_name”: “First Last”,
“password”: “PASSWORD”,
“feature”: {
“zoom_phone”: “true”,
“zoom_one_type”: 16
}
}
}
